I don’t understand how to do this. “Finding the absolute value of an expression”
Answers
Answer:
To find the absolute value of an expression think of every number as a positve one. So if you see a number in parenthesis that is negative, make it a positive and then solve! If a number is already positive, it is already in its absolute value form.
For example:
(-4) + (2)= ?
We know that every number has to be positive to be absolute value so we would make -4 a 4 and 2 is already in absolute value so we will keep it as it is and solve.
4-2=?
Now we will solve the expression as normally which would be 2. Hope this helps!
Step-by-step explanation:
Answer:
So from what I see on the screen you have to find more than one way to solve for each problem but first you need to know what you are trying to solve for so lets go to the second problem
15+6
so 15 + 6 = 21 and now you can put 21 at the right end and in the middle you would make 2 different problems to put in the middle like 10+11 and 3 x 7
so it would look like this for the second one
[15+6] = 10+11 = 3 x 7 = 21
I hope this helps you and good luck. :D
Determine the center and radius of the following circle equation:
x² + y² - 10x + 20y + 89 = 0
Answers
Answer:
The center is ( -5, -10) and the radius = 6.
Step-by-step explanation:
Convert the equation to standard form by completing the square;
x^2 + y^2 - 10x + 20y + 89 = 0
x^2 + y^2 - 10x + 20y = -89
x^2 - 10x + y^2 + 20y = -89 Completing the square:
(x + 5)^2 - 25 + (y + 10)^2 - 100 = -89
(x + 5)^2 + (y + 10)^2 = -89 + 125
(x + 5)^2 + (y + 10)^2 = 36
Comparing this to the standard form:
( x - h)^2 + (y - k)^2 = r^2
- we see that the center is ( -5, -10) and the radius = 6.

What is the distance between point A and point B?
Answers
Answer:
the answer is B. The square root of 45.
Step-by-step explanation:
use the pythagorean theorem.
1. Find the side lengths of A and B, since you're trying to find the hypotenuse.
2. [tex]A^{2} + b^{2} =c^{2} \\3^{2} +6^{2} =c^{2} \\9+36=c^{2} \\45=c^{2} \\c=\sqrt{45}[/tex]
The distance between point A and point B is √45.
What is the Pythagorean theorem?The Pythagorean theorem states that the sum of the squares of the sides of a right-angled triangle is the square of the length of the hypotenuse.
The distance between A and B can be found as follows:We can draw a horizontal line parallel to the x-axis through point A. Now draw a vertical line parallel to the y-axis and intersects the horizontal line. Now join A and B.
The resultant triangle is a right-angled triangle.
We can use the Pythagorean theorem:
AB² = (5 - 2)² + (9 - 3)²
= 3² + 6²
= 9 + 36
= 45
AB = √45
Therefore, we have found that the distance between point A and point B is √45.

zero without changing the form of the expression?
P(x) = -3x? + 432x - 1680
b) P(x) = -3(x-4)(x - 140)
P(x) = -3(x - 72)2 + 13872
2) Find a price, which gives a profit of zero.
Answers
Answer:
1. (B)P(x) = -3(x-4)(x - 140)
2. $140
Step-by-step explanation:
(1) Given the profit function, P(x) where x is the price, the expression which reveals the price which gives a profit of zero without changing the form of the expression is:
P(x) = -3(x-4)(x - 140)
This is as a result of the fact that equating it to zero immediately yields the zeros of the quadratic polynomial.
(2)When the profit, P(x)=0, then using the expression above we have:
[tex]P(x) = -3(x-4)(x - 140)\\Since -3\neq 0, then:\\x-4=0$ or x-140=0\\x=4 or x=140[/tex]
A price of $4 or $140 as the case may be gives a profit of zero.

PLEASE HURRY
Answers
Answer:
Option D
One worker works for much fewer hours than everyone else
Step-by-step explanation:
First of all, we will need to clarify the concepts.
The median of a distribution is the middle number in that distribution, after the values have been arranged in either an ascending or descending order.
The mean is a weighted average of a distribution.
The mean has the characteristic of usually being affected by extremely low or extremely high values.
In our case, we have a relatively low value in terms of hours worked. This means that in the distribution, the worker that worked only 20 hours, will affect the mean hours worked by all the workers, making it lower than the median value.
Means give better results, when used to analyse distributions with smaller ranges.

so, he also eliminated the y-terms and got the equation 0 = 0, so he thought that the system of equations must have an infinite

What is the point-slope form of a line with slope -3 that contains the point

B. x + 1 = -3(y-10)
C. y + 1 = -3(x-10)
D. y + 1 = 3(x-10)
Answers
Answer:
C
Step-by-step explanation:
Since we have a point and a slope, we can use the point slope formula.
The point slope formula is:
[tex]y-y_{1} =m(x-x_{1})[/tex]
where m is the slope, and (x1, y1) is the point given.
We know that the slope is -3, and the point given is (10, -1)
Therefore, our m is -3, x1 is 10, and y1 is -1.
y- -1 = -3(x-10)
y--1 is the same as y+1
y+1= -3(x-10)
Therefore, choice C is correct.

The solution of the system of equation is (4, 2) which is correct option(A).
What is equation?Equation is the defined as mathematical statements that have a minimum of two terms containing variables or numbers is equal.
Given the two systems of equations,
-3x + 5y = -2
3x + 7y = 26
Adding the both equations
-3x + 5y + 3x + 7y = -2+26
12y = 24
y = 2
Substitute the value of y in any one of the equations,
3x + 7 y = 26
3x + 7(2) = 26
3x = 26-14
3x = 12
x = 4
Hence, the solution of the system of equation is (4, 2).

Find the inverse of f( x ) = -( 1 / 3 )x + 1
STEP 1: Stick a "y" in for the "f(x)" guy:
y = -( 1 / 3 )x + 1
STEP 2: Switch the x and y
( because every (x, y) has a (y, x) partner! ):
x = -( 1 / 3 )y + 1
STEP 3: Solve for y:
x = -( 1 / 3 )y + 1 ... multiply by 3 to ditch the fraction ... 3x = -y + 3 ... ditch the +3 ... subtract 3 from both sides ... 3x - 3 = -y ... multiply by -1 ... -3x + 3 = y ... y = -3x + 3
STEP 4: Stick in the inverse notation, f^( -1 )( x )
f^( -1 )( x ) = -3x + 3
